I've stayed at Docklands Private Collection of Apartments 4 times now and seem to always return. Check in is always a breeze and the managers are always friendly and helpful.
The 3 apartments we have stayed in have been absolutely beautiful with huge rooms and vies to die for. I could sit in the lounge all night and see the city lights and the harbour.
It's perfectly situated for football at Etihad Stadium (which you can see from your room). Only a 2 minute walk from Docklands.
Food is easy to find with numerous restaurants directly under the apartments.
I can highly recommend a stay with Private Collection, you will not be disappointed :-)
